Definitions
- This invention relates to a photographic element incorporating an antihalation or acutance dye.
- Light sensitive recording materials may suffer from a phenomenon known as halation which causes degradation in the quality of the recorded image. Such degradation may occur when a fraction of the imaging light which strikes the photosensitive layer is not absorbed but passes through to the film base on which the photosensitive layer is coated. A portion of the light reaching the base may be reflected back to strike the photosensitive layer from the underside. Light thus reflected may, in some cases, contribute significantly to the total exposure of the photosensitive layer. Any particulate matter in the photosensitive element may cause light passing through the element to be scattered. Scattered light which is reflected from the film base will, on its second passage through the photosensitive layer, cause exposure over an area adjacent to the point of intended exposure. It is this effect which leads to image degradation.
- halation causes degradation in the quality of the recorded image. Such degradation may occur when a fraction of the imaging light which strikes the photosensitive layer is not absorbed but passes through to the film base on which the photosensitive layer is coated. A portion of the light reaching the base may be reflected back to strike the photosensitive layer from the underside
- Silver halide based photographic materials are prone to this form of image degradation since the photosensitive layers contain light scattering particles.
- the effect of light scatter on image quality is well documented and is described, for example, in T. H. James "The Theory of the Photographic Process", 4th Edition, Chapter 20, Macmillan 1977.
- a similar effect may be achieved by a light absorbing layer interposed between the photosensitive layer and the base.
- This construction described as an "antihalation underlayer” is applicable to photosensitive coatings on transparent or non-transparent bases.
- a light absorbing substance may be incorporated into the photosensitive layer itself, in order to absorb scattered light. Substances used for this purpose are known as "acutance dyes". It is also possible to improve image quality by coating a light absorbing layer above the photosensitive layer of a wet processed photographic element. Coatings of this kind, described in United States Patent Specification No. 4 312 941 prevent multiple reflections of scattered light between the internal surfaces of a photographic element.
- Triarylmethane and oxonol dyes in particular, are used extensively in this connection. There is, however, a need for antihalation and acutance dyes which absorb in the near infrared region of the spectrum. Dyes of this type are required for recording materials which are spectrally sensitised to near infrared wavelengths, for example, materials which are designed to record the output of near infrared lasers.
- Coatings of infrared absorbing pigments such as carbon black may be used, however, the use of this material is objectionable since it does not decolourise during processing and must therefore be coated in a binder which dissolves in developing solution allowing the carbon black to wash off causing objectionable contamination of the developer.
- Coatings of antihalation or acutance dyes which absorb in the visible region of the spectrum are usually required to become colourless during processing of the photographic material, either by washing out or chemical reaction in wet processing techniques or thermal bleaching during heat processing techniques.
- Cyanine dyes are well known in the photographic art and are extensively used as spectral sensitiers for silver halide based materials. Cyanine dyes are not usually used or considered suitable for antihalation or acutance purposes owing to their limited solubility in aqueous media and especially to their inability to decolourise completely during photographic processing when present in large quantities.
- a photographic element comprising one or more photosensitive layers and, as an antihalation or acutance dye in an amount to provide a transmissive optical density of greater than 0.1 at ⁇ max of the dye at least one compound of the formula: in which
- the heterocyclic nuclei formed by Z 1 and Z 2 may be any of the wide range of nuclei known in the cyanine dye art.
- Z 1 and Z 2 each represent the non-metallic atoms necessary to complete a heterocyclic nucleus containing 5 to 6 atoms in the heterocyclic ring, the nucleus optionally possessing substituents.
- the heterocyclic ring is composed of ring atoms selected from C, N, 0, S and Se. Examples of such heterocyclic nuclei include:
- Z 1 and/or Z 2 complete a benzothiazole nucleus or a 3,3-dialkylindolenine nucleus.
- the groups R 1 and R 2 contain less than 8 carbon atoms. More preferably R 1 and R 2 are lower alkyl groups containing up to 4 carbon atoms.
- the alkyl groups may contain any substituent which does not deleteriously effect the properties of the dye as known in the cyanine art. Suitable substituted alkyl groups include alkoxy-alkyl, benzyl and carboxy-alkyl.
- R 3 and R 4 represent a hydrogen atom or a lower alkyl group containing 1 to 4 carbon atoms.
- R 5 to R 8 are hydrogen.
- certain substituted cyclopentanones are commercially available which may be used as intermediates in the preparation of the dyes of formula (I), e.g. 3-methylcyclopentanone and 3-phenylcyclopentanone and accordingly one of R 5 to R 8 may readily represent these substituents.
- the cyclic acid nuclei completed by the groups Q 1 and Q 2 have the ring atoms selected from C, S, N, O and Se. Suitable moieties are derived from the following nuclei which may additionally possess substituents: 1,3-indandione, pyrazolone, isoxazolone, e.g.
- a preferred cyclic nucleus completed by Q 1 and Q 2 has the general formula: in which:
- the dyes of formula (I) absorb in the near infrared having a very low visible absorption whilst retaining a high extinction coefficient at the absorption maximum.
- the dyes of the invention have extinction coefficients at their maximum absorption wavelength (typically 800 nm or higher) of the order of 2.5 x 10 5 to 3.0 x 10 5 .
- maximum absorption wavelength typically 800 nm or higher
- the absorption has generally fallen to approximately 10% of this value and at 650 nm the aborption is down to approximately 2% of the value, as measured in methanolic solution.
- the dyes may be incorporated into wet processed photographic or photothermographic elements as acutance dyes according to conventional techniques.
- the dyes may also be incorporated into antihalation layers according to techniques of the prior art, for example, in the case of wet processed photographic elements, as an antihalation backing layer, an antihalation underlayer or as an overcoat. It is also anticipated that similar nonamethine dyes would be suitable for use as acutance and antihalation dyes.
- the quantity of sensitising dye used in the emulsions disclosed in United States Patent Specification No. 2 955 939 is in the general range 5 to 100, usually 10 to 20 mg per litre of emulsion whereas for acutance purposes in accordance with the invention the dyes would generally be used in the range 200 to 1000 mg per litre of emulsion.
- the dyes of formula (I) are added to the photographic element in an amount to provide a transmissive optical density of greater than 0.1 at ⁇ max of the dye.
- the coating weight of dye which will provide the desired effect is from 0.1 to 1 mg/dm 2 .
- dyes of formula (I) in which the moiety completed by Q 1 and Q 2 contains one or more bulky aliphatic or predominantly aliphatic groups have particular advantages for use in the photographic elements of the invention.
- Substituents of this type have the benefit of enhancing the solubility and facilitating the colloidal dispersion of the dyes in an aqueous gelatin-surfactant mixture, this being the normal medium for coating silver halide photographic materials.
- dyes of formula (I) not possessing such bulky substituents may on coating and drying, lose some density at the primary near infrared absorption peak and develop a secondary shorter wavelength absorption peak. It has been found that this undesirable phenomenon is inhibited or entirely suppressed by the incorporation of bulky aliphatic groups onto the moiety completed by Q 1 and Q 2.
- Q 1 and Q 2 When the moiety completed by Q 1 and Q 2 contains a single bulky aliphatic or predominantly aliphatic group, this group must contain at least 8 and preferably at least 10 carbon atoms. When two aliphatic or predominantly aliphatic groups are present the two groups must together contain at least 8 and preferably at least 10 carbon atoms. Predominantly aliphatic groups refer to groups in which at least half the carbon atoms present are in the form of aliphatic carbon atoms. Aliphatic as used herein includes cycloaliphatic, e.g. cyclohexyl.
- the aliphatic groups are alkyl groups containing at least 8, more preferably at least 10, carbon atoms.
- a particularly preferred moiety completed by Q 1 and Q 2 is that of formula (II) defined above in which at least one of R 9 and R 10 are aliphatic groups of at least 8 carbon atoms or R 9 and R 10 are both aliphatic groups together having at least 8 carbon atoms.
- the dyes of the formula (I) may be prepared according to the methods described in United States Patent Specification No. 2 955 939. The synthesis involves the following stages:
- the assymetrical dyes may be prepared by a related two-step mechanism.
- Dodecylamine (370 g) was placed in 80/100°C fraction petroleum ether (1.5 litre) and stirred in a flask fitted with a dipping thermometer, tap funnel and reflux condenser. A mixture of ethyl isocyanate (142 g) and petroleum ether (150 ml) was run in slowly whilst external cooling was applied to the flask. The temperature was allowed to reach but not exceed 50°C. The mixture was stirred for 1 hour after the addition was complete, maintaining the temperature at about 50°C. The reaction was then allowed to cool and the copious white precipitate (which had begun to separate as soon as the isocyanate addition commenced) was filtered off, pressed well and washed with about 300 ml petroleum ether. The white mass was dried in vacuum at 50°C to give a quantitative yield (512 g) with a melting point of 84 to 87°C. The product was not subjected to any further purification before use.
- magenta impurity tends to mask the presence of the product.
- the crude material (14.0 g) was crystallised from methanol (approx. 5 litres) and collected on a filter, where it was carefully washed with more methanol to remove the last traces of the magenta impurity.
- the yield was 9.6 g and the product melted at 243°C with decomposition. Concentration of the filtrate gave a further 1.3 g of product with the same quality.
- the dye was prepared according to the.procedures of Example 1 starting from octadecylamine and iso- cyanatomethane.
- Dye (0.04 g) was dissolved in 2-propanol (20 ml) at 60°C. The dye solution was added with rapid stirring to a 6% solution of gelatin (72 ml) containing sodium dioctyl sulphosuccinate (0.25 g) as surfactant at 60°C. Formaldehyde (2 ml, 4%) was added to the mixture. The dye-gelatin mixture was coated at 0.8 cm 3 of solution per square decimetre of subbed polyester base and dried. The characteristics of the dye-gelatin coatings are reported in the following Table IV.
- the ratios of near infrared maximum absorbance of the dye coatings to the average absorbance between 600 and 700 nm provide a measure of the effectiveness of the dyes for antihalation coatings in which the two main requirements are: high near infrared density, and low visible blue colouration (i.e. low average absorbance between 600 and 700 nm). It can be seen that the highest values of this ratio were measured on coatings made from dyes possessing bulky aliphatic groups in the moiety completed by Q 1 and Q 2 .
- Dye 23 (0.01 g) was dissolved in chloroform (2 ml) and added to a solution of polyvinylbutyral polymer (1 g) in butan-2-one (10 ml). The resulting solution was coated at a wet thickness of 75 pm onto polyester base and dried. The resulting coating, suitable for an antihalation layer for infrared sensitive photothermographic materials was colourless in visual appearance but exhibited an optical absorption of 0.3 at 845 nm.
- a 2% iodobromide emulsion was prepared by balanced double jet emulsification to give cubic grains of 0.16 pm mean edge length.
- the emulsion was conveniently sulphur and gold sensitised.
- the emulsion was spectrally sensitised to the near infrared by the addition of 13 mg of 3,3'-diethylthia-tricarbocyanine iodide as a 0.04% solution in methanol per mole of silver.
- the emulsion was split into 9 portions which were coated as follows:
- the nine coatings were imaged with near infrared light focussed from a test target consisting of an array of fine lines using near infrared light from a 500 W tungsten bulb filtered with a Kodak Wratten No. 88A filter.
- the exposed samples were developed and fixed using conventional black and white processing solutions.
- Dye 29 (15 mg) was dissolved with warming in methanol (15 ml) and added with stirring to 10% ethylcellulose in 2-butanone (30 ml). The solution was coated at a wet thickness of 65 pm onto unsubbed polyester base and dried. The layer, which had a faint blue visible appearance, had a peak infrared absorption of 0.38 at 815 nm.
- Dye 8 coated in the same way had a peak absorption of 0.24 at 812 nm.
- a chlorobromide emulsion (64% chloride) was prepared by balanced double jet emulsification to give cubic grains of 0.28 ⁇ m mean edge length. This emulsion was conventionally sulphur and gold sensitised, and spectrally sensitised to near infrared radiation from 700 to 850 nm.
- These coatings were imaged to infrared light by focussing the output of a laser diode at 815 nm into a s line of width approximately 100 pm at the emulsion surface of the film.
- the duration and intensity of the exposure was chosen so as to give, on processing the samples in conventional black and white developing and fixing solutions, a line image of which the central density just reached the maximum (optical density of 3.5 above base + fog) obtainable on the emulsion layer used.
- the density profile across this line image was then recorded using a microdensitometer, and the width of the line measured at densities of 0.5 and 1.0 above base + fog, thus giving a direct evaluation of line spread due to halation.
- Table V shows the heavy halation in the unbacked Sample 1 and the diminished halation in Sample 2, backed with Dye 33, both compared with Sample 3 in which halation is absent.
- a conventional silver behenate (thermally developed silver) preparation e.g. as disclosed in British Patent Specification No. 1 565 593, was spectrally sensitised to near infrared radiation and coated as follows:
- the coatings were each imaged with the same amount of exposure from a single narrow line of infrared light at 815 nm (as used in Example 7). Processing was by heating for 10 s on a drum at 125°C, and gave image lines of peak density 1.1-1.2 above base + fog. The density profile across the lines were measured with a microdensitometer, and line widths at densities of 0.3 to 0.5 above base + fog obtained, giving a direct measure of image spread due to halation.
- Table VI shows the severe halation occuring on the unbacked Sample 1, and the reduction of halation using the dye backed Samples 2 to 4, all compared with the halation-free Sample 5.
